Description
CM-S221 safety switches are a coded magnet safety switch
for use in machine guarding applications.
Designed for use in applications where increased security is
required, the CM-S221 has a coded magnetic actuator and
cannot be fully operated with a single magnet.
The CM-S221 switches are designed to be connected to a
safety control circuit which has less than 0.5 Amps
inrush current.
The CM-S221 is manufactured in a robust ABS housing and
fully sealed to IP67 and can be used in wet or dusty
environments.
With correct installation, the CM-S221 safety switches comply
with the guidelines given in EN1088.
Operation
When the safety switch and actuator are within the specified
operating range (see table on page 3 for switching
distances), the N/C contacts will be closed and the N/O
contacts will be open.
When the actuator moves out of the operating range, the N/C
contacts will open and the N/O contacts will close. Both the
N/C and N/O contacts may be used for safety.
The CM-S221 safety switch and actuator are designed to
approach each other from most angles. When the switch is
closed the targets on the printed face of the switch must be
aligned.
Applications
Interlocked guards where door locking is not required.
